Description

Technical Field

[0001] This utility model belongs to the technical field of hot-dip galvanizing equipment, and in particular relates to a vibration device for hot-dip galvanizing. Background Technology

[0002] After hot-dip galvanizing, excess molten zinc often remains on the surface of the workpiece. These residues not only affect the product's appearance but may also reduce the corrosion resistance of the coating. Removing residual molten zinc is a crucial step in ensuring product quality during hot-dip galvanizing. Vibration removal is an important technique for treating residual molten zinc on the workpiece surface. It primarily utilizes mechanical devices to generate high-frequency or low-frequency vibrations, causing the unsolidified molten zinc on the galvanized workpiece to separate from the substrate due to inertia. Its core principle lies in using vibration energy to break the adhesion between the molten zinc and the workpiece surface, while simultaneously using gravity to allow the molten zinc to drip off naturally. This process is usually performed immediately after the galvanized workpiece leaves the zinc bath, when the molten zinc is still molten and easier to shake off. It is often used for structural components. In terms of advantages, the vibration method requires no chemical additives, does not alter the metallic composition of the zinc layer, and can process multiple workpieces simultaneously, making it significantly more efficient than manual wiping.

[0003] Comparing with Chinese Patent Publication No. CN222770932U, a vibration device for hot-dip galvanizing is disclosed. This device includes two vibrators, each connected at its top to a lifting device. Each vibrator has a hook at its base, and a lifting device with a hammock below each vibrator is provided. The lifting device includes hook assemblies corresponding to the two vibrators, with one end connected to the vibrator and the other end connected to the hammock. A connector connects the two hook assemblies above the hammock. The connector links the two vibrators, and the vibration force generated by the vibrator increases continuously during transmission through the connector, thereby improving the vibration effect on the degalvanized workpiece and enhancing the degalvanizing effect.

[0004] However, the vibrations mentioned above are transmitted through non-rigid connections such as hooks, which can easily lead to interruption of transmission or reduction of vibration amplitude, seriously affecting the zinc removal effect of the workpiece. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a vibration device for hot-dip galvanizing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vibration device for hot-dip galvanizing includes a cantilever assembly for circumferential rotation and vertical bending for hot-dip galvanizing, and a suspension assembly mounted on the top of the cantilever assembly for elastic support and rotational direction change. A fixture is mounted on the suspension assembly for clamping the workpiece for hot-dip galvanizing and vibrating to remove zinc. The cantilever assembly includes a fixed base, a rotating seat mounted on the fixed base, a rotary motor disposed below the rotating seat, and a folding mechanism mounted on the rotating seat. The suspension assembly includes a support plate, with four transition mechanisms evenly distributed at the four corners of the support plate for elastic support and vibration amplification. A connecting seat is disposed behind the support plate, and a third motor is disposed on one side of the connecting seat. The fixture includes a movable frame, with a vibrator mounted behind the movable frame. Two fixed clamping rods are symmetrically mounted at the bottom of the movable frame, and two movable clamping rods are symmetrically arranged above the fixed clamping rods. A pneumatic mechanism is disposed at the top of the movable frame to provide clamping power, and the pneumatic mechanism pushes and drives the movable clamping rods to move.

[0008] Furthermore: the folding mechanism includes a first motor installed on one side of the rotating seat, a first arm installed at the output end of the first motor, a second motor installed at the top of the first arm, and a second arm installed at the output end of the second motor.

[0009] Furthermore, the rotating seat adopts a double-plate structure.

[0010] Furthermore, the transition mechanism includes a limiting slide rod that is slidably connected to the support plate, the limiting slide rod is provided with a spring, and the rear end of the limiting slide rod is provided with a limiting baffle.

[0011] Furthermore, the limiting slide bar is made of 45 steel and is threadedly connected to the movable frame.

[0012] Furthermore, the pneumatic mechanism includes a telescopic cylinder fixedly installed at the top of the movable frame, a limit slide is installed at the telescopic end of the telescopic cylinder, and the movable clamping rod is installed at both ends of the limit slide.

[0013] Furthermore, the distance between the movable clamps is less than the distance between the fixed clamps.

[0014] Furthermore, both the fixed clamp and the movable clamp are covered with anti-slip sleeves.

[0015] Compared with existing technologies, the beneficial effects are:

[0016] 1. The fixture adopts a pneumatically driven symmetrical clamping rod design (fixed clamping rod + movable clamping rod + anti-slip sleeve). The clamping force is precisely controlled by the telescopic cylinder, and the anti-slip sleeve on the surface prevents the workpiece from sliding, ensuring the continuity of vibration transmission. Through the innovative combination of mechanical vibration and elastic system, the technical bottleneck of zinc residue in hot-dip galvanizing process has been overcome. It has the dual advantages of efficient zinc removal and safe operation, and is suitable for batch automated production scenarios.

[0017] 2. The unique layout of "small-pitch movable clamping rods + large-pitch fixed clamping rods" creates a mechanical self-locking effect, ensuring that the workpiece does not shift during high-frequency vibration;

[0018] 3. The suspension assembly, through a four-corner spring-slide rod transition mechanism (45 steel limit slide rod + spring + limit baffle), amplifies the initial vibration force of the vibrator through elastic energy storage, forming continuous and powerful vibration, significantly enhancing the zinc liquid removal effect. After the vibrator starts, the system forms a three-stage energy transfer chain: vibrator → movable frame → elastic suspension assembly → workpiece clamping. The reciprocating compression of the springs not only amplifies the vibration but also prevents mechanical fatigue fracture through the limit baffles, thus increasing the zinc liquid removal rate.

[0019] 4. The cantilever assembly adopts a dual-motor driven folding mechanism (first / second arm + rotating seat) to realize the compound motion of workpiece circumferential rotation and vertical bending, which solves the problem of traditional fixed fixtures being difficult to adjust at multiple angles and adapts to the galvanizing requirements of workpieces of different shapes.

[0031] In this embodiment: the suspension assembly includes a support plate 201, with four transition mechanisms evenly distributed at the four corners of the support plate 201 for elastic support and vibration amplification. A connecting seat 202 is provided behind the support plate 201, and a third motor 203 is provided on one side of the connecting seat 202. The transition mechanism includes a limiting slide rod 204 slidably connected to the support plate 201, a spring 205 is provided on the limiting slide rod 204, and a limiting baffle 206 is provided at the rear end of the limiting slide rod 204. The limiting slide rod 204 is made of 45 steel and is threadedly connected to the movable frame 301. The third motor 203 drives the support plate 201 to rotate through the connecting seat 202, and drives the movable frame 301 to move through the limiting slide rod 204. At the same time, during dezincification, the vibration of the movable frame 301 continuously increases under the elastic force of the spring 205 on the limiting slide rod 204, while the limiting baffle 206 prevents the limiting slide rod 204 from falling off the support plate 201.

[0032] In this embodiment: the fixture includes a movable frame 301, a vibrator 307 is mounted on the rear of the movable frame 301, two fixed clamping rods 302 are symmetrically mounted on the bottom of the movable frame 301, and two movable clamping rods 304 are symmetrically arranged above the fixed clamping rods 302.

The vibration of the movable frame 301 is continuously increased under the elastic force of the spring 205 on the limit slide rod 204.
